Nervous System Divisions
The brain and spinal cord division
What is the CNS?
The two ions of the resting membrane potential
What are Sodium and Potassium?
The structures that receive signals on a neuron
What are dendrites?
What are the SNS AND the PSNS?
The membrane structures that protect the CNS
What are the meninges?
The non-brain, non-spinal cord nervous systems
What is the PNS?
The Resting Membrane Potential (the value of the charge)
What is -70 mv?
The structure(s) that send signals on a neuron
What are axons?
The name of a clump of cell bodies in the ANS (not in the spinal cord)
What is a ganglion?
The cell type that produces cerebrospinal fluid
What are ependymal cells?
The sensory nervous system division
What is the Afferent nervous system?
The ion of depolarization AND the new charge
What are Sodium and +30mv?
The non-conductive substance on axons that speeds up a signal
What is myelin?
The effects of the SNS on heart rate AND the effect of the PSNS on gut motility
What are INCREASE and INCREASE?
The most crucial 1/4 section of the brain AND the specific section of it that controls heart rate, subconscious breathing, coughing, sneezing, etc.
What are the brain stem AND the Medulla of the brainstem?
The motor nervous system division
What is the efferent nervous system?
The ion of Repolarization AND the direction those ions go
What is Potassium? and they exit the cell
The chemical portion of the message that a neuron releases to the next cell in line (generic term)
What are neurotransmitters?
The length of the first neuron in the SNS and the length of the first neuron in the PSNS
What is short? Which is long?
The center 1/4 of the brain, containing the Hypothalamus
The rest and digest AND the fight or flight nervous systems
What are the PSNS and the SNS?
The reasons why the cell may begin to depolarize, AND the threshold voltage for depolarization
What are Light, Heat, Pressure, Vibrations? And what is -55mv?
The conductive spots on an axon; gaps between the non-conductive material... AND the type of conduction that jumps from gap to gap
What are nodes of Ranvier? And what is saltatory conduction?
The effects of the SNS on bronchiole diameter AND the effect of the PSNS on the bladder walls
What are dilation AND constriction?
The lobe of the cerebrum that controls conscious skeletal muscles, and the lobe of the cerebrum with conscious knowledge of touch
What are the frontal lobe (precentral gyrus) AND the parietal lobe (postcentral gyrus)?
